Noise in Laguna of the year 1999

Hello.
I would like someone to help me with a problem that I have.
I have a 99 RXE 1.6 16 VY lagoon makes me a lot of noise when it circulates more than 80 km/h. I have looked like bearings and bearings and they are fine. The escape tube is not broken.
Another problem is that I don't know how the air conditioner console is disassembled to change the bulb.
